Im pretty sure my ex business partner hacked into my computer, shes been in my microsoft account, deleted files, etc. and my desktop. she used to work for a company called Justice Traxx and they pretty much hacked into criminals computers for the FBI for a living. I dont know how to prove or how to find how shes gotten into my comp. Can anyone help? Is there a way to permanently change my IP address but not through a VPN or anything?
